SULKY- SAME PLAOE.

PLOW.

SPECIFICATION forming part of Letters Patent No. 240925, dated May 3,1881.

Application filed October 19, 1880. (No model.)

To all whom it may concm Be it known 'that I, HORACE E. REEVES, a'citizen of the United States, residing at Fort Dodge, in the county ot'Webster and State of Iowa, have inveuted certain new and usefulImprovements in Sulky-Plows; and Ido hereby declare the following to bea full, clear, and exact description ot' the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompauyiugdrawings, and to theletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements iu sulky-plows, being an additionto those set forth in my Patent No. 230,&97, July 27,1880.

The objects of my present improvenents are to increase the faeility ofguiding, raising, and lowering the front end ot' the plow-beam to givethe plow greater freedom and promptness of action in swinging back onmeeting an obstruction, and to simplfy the usual means by which theseobjects are sought to be accomplished.

The mechanisns constituting my improvements are illustrated in theacconpanyin g drawings, in which- Figure 1 is a perspective Viewthereof; Fig. 2, a side view, and Fig. 3 a detail View, of thecrauk-aXle and its bearings. Fig. 4 is a detail view of the clamp inthree parts, showing the connection of the lower part-s With theplowbe'am, and also showing the inner portion of the top part and theparts grooved to form a hearing for the crank-aXle.

Similar letters refer to similar parts throughout the several views.

A represents the wheels, the crank-axles a of which are attached to androtate upon the ends of the aXle-shat't C.

To the inner ends of the upper arms of erankaxles a are rigidly attachedthe spring-levers E, which move along the outer sides of and operateupon the arched notched plates F. The plates F are fixed to the outerends of the hollow or sleeve axles B B'. The Construction of theselevers and their operation upon the landside and i'urrow are the same asshown and described in myPatent No. 230,497, and are not, therefore,particularly set forth here.

G is an aXle-shat't having a double crank, b, situated to one side ofits center, on the furrow side of the plow, and in such a position as tobring the plow the required distance from the furrow-wheel.- Theopposite ends of the doublecrank axle pass through sleeves B B' and alsothrough the hollow wheel-axles a, in both of which it is free to rotatewhen the plowis raised or lowered. The double oran k has also a bearing,and rotates in clamp V, by which itis firmly joined to the plow-beam D.The clamp V is constructed of three grooved plates, l 2 3, as shown inFig. 4, l being the top plate and 2 and 3 the bottom plates. The lowerones are provided with lugs, and bolted to opposi te sides of theplow-beam at a point shown in Figs. 1 and 2. The clamp as thusconstructed and arranged forms a bearing, iu which the axle C, locatedabove the plow-beam, freely rotates, and also securelyconnects the beamand doublecrank axle, so that both may be raised together. The plow-beamD, backward from the clamp V, curves abruptly upward and then downward,and has attached to its lower end the plow X. From the clamp forward theplow-beam has first a slight downward and then an upward curve, and 'atits forward end is attached by a break-pin,f, to a swivel, G, huug inthe yoke H. The swivel G has a screw-pin, g, which extends upwardthrough the yoke, and is there provided with a Washer, h, and tailnut i,by means of which it can he raised and lowered, and with it theplow-beam l). The yoke H is somewhat triangularin form, and iscoustructed of the lower cross-piece,j, the side arms, 76 Ic, and theupper cross-piece, l. It is supported in 'a fra-me consisting of thetongue L, the wooden beam or bar M, and the twisted metallie braces N N.The rear ends of the frame L M N N are firml y secured to the bosses1917 of the sleeves B B'.

On the frame L M 'N N there is also supported an upright seat-frame, O,composed of two verticalside arms and cross-piece. The lower ends of thearms are turned at right angles therewith, and one end is bolted to thetongue L and the other to the beam M. It is further strengthened andsupported by the brace o, bolted at one end to the tongue L and at theother end to the under side of the upper cross-piece of the seat-frame.

From the seat-frane O projects upwardly the eurved standard P, to whichis attached the seat R.

On one side and to the front of the driver s seat is a hand-lever, S. Itis attached at its lower end to the inner side of tongue L by pivot t.Itis sustained or held firmlyin place When the plow is raised from theground, and supported while turnin g, or when not in use, by means of avertical spring, e, bolted to the tongue L, near the yoke H, and havingits upper end beveled, with a noteh to receive and hold said lever. Tothe inner side of this lever, and a short distance above where it ispivoted to the tongue, is seeured the arm T. This arm is connected by alink-joint, s, to the curved semicircular arm U. The link-joint s andthe arm T are united by a wooden break-pin, t'. The lower end of arm Uis securely attached to the plow-beam D by the same bolts that hold theplates of clamp V to the plow-beam.

The operation of the plow is as follows: The wheels are lifted andlowered and held in place, in guiding and turning the plow, by means ofthe levers E and notched plates F, as is usual in this class of plows.By means of hand-lever S, connected with arms TUand plow-beam D, thedriver is enabled to raise the plow while turning, and the samearrangement obviates the necessity of looking the lever when the plow isin use. When the plow meets an obstruction the plow-beam D, double crankaxle, and curved arm and hand-lever, all yield at Once andsimultaneously to the pressure. It' the obstruction is small, sufficientyield is allowed, by reason of the peculiar arrangenent of the partsabove mentioned and the connection of the plow-beam to theswivel, topermit the plow to be raised without breaking the break-pin but if theobstruction is considerable, the yield cuts the break-pin, and the plowis cleared at once of the obstruction, and by reason of the Constructionof the curved arm will be raised, if necessary, as high as the driver sseat. The hand-lever is not locked, and the slightest obstruction is atonce responded to by the lever and its connections.

The screw-pin g and the tail-nut' ou the upper end of the swivel G areused to adjust the plow to a level and retain it in that position whileat work, thus overcoming the teudency of said plow to ride upon itspoint or nose.

I provide two or more holes in the lower cross-piece, j, of the yoke H,to provide for the adjustnent of the clevis to one side or the other, inorder that the plow may take in more or less land, as desired.

Having thus described my invention, what I claim as new is- 1. Thecombination of the hollow sleeves or easings B B', the notched plates F,rigidly attached thereto, and the doublecrank axle C, substantially asdescribed.

2. The yoke H, provided with the swivel G, screw-pin g, and tail-nut i,in combination with the plow-beam D, substantially as described.

3. The eombination ot' the lever S, vertical spring-catch e, jointedstraight arm T, curved arm U, and plow-beam D, substantially asdescribed.

4. The combination of the jointed bar or arm T, lever S, curved arm U,and break-pins f and t', whereby, in meeting an obstruction, the plowand beam are made free to rise clear from the ground, and, it'necessary, as high as the driver s seat.

5. The combination oflever S, arm T, curved arm U, clamp V, andplow-beam D, substantially as described.

6. The combination of the yoke H, supporting-frame L M N N, and sleevesB B', the latter provided with the bosses p p, to which the rear end ofthe supporting-frame is Secured;

In testimony whereof I afl'x my signature in presence of two witnesses.
